Testing Brake Booster
 

Hey everyone

I've been attempting to restore my 190E's brakes to their former glory and I'm going to move back to the stock master and booster.

I have the booster here but I'm not sure if its any good. Its been sitting on my shelf for a few years now. Is there any way to bench test it?

I've got to order a new master. :(

Did you ever figure out how to test it?

Not externally. I just installed it in the car. The booster is fine.
